CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 297,765, dated April 29, 1884.

Application. filed January 23, 1884. (No model.)

To all whom it may concern:

Be it known that I, A. J UDsoN CHAPEL, a citizen of the United States, residing at Arkansas City, in the county of Cowley and State of Kansas, have invented certain new and useful Improvements in Automatic Oar-Couplings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of the specification, in which Figure 1 is a plan View of my improved automatic carcoupling, representing the drawbars as coming together in the act of coupling. Fig. 2 is a plan view of the link. Fig. 3 is alongitudinal vertical section of the draw-- bar, showing a side .view of the coupling-pin. Fig. 4 is a front elevation of a draw-bar with the coupling-pin in place and .the lever for raising and lowering the same. Fig. 5 is a side view of the link, showing its beveled ends for engaging the beveled outer endsof the tongues of the pins to lift the latter; and Fig. 6 is a horizontal sectional view of the coupling-pin, and shows, also, the shape of the coupling-pin holes in the top and bottom faces of the draw-bar.

My invention relates to improvements in automatic couplers; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims.

The draw-bars A of my improved automatic car-coupling are of the ordinary construction, with flaring mouths to receive the link in coupling cars, the only difference in construction between my construction and the ordinary form of draw-bar being the form of the holes in the upper and lower faces of the drawbar, as shown in Fig. 6, which conform to the peculiar shape of the coupling-pin, which,

is also shown in horizontal section in said figure.

B B D represent the coupling-pin, which passes through the correspondingly formed holes in the upper and lower faces of, the drawbar and through the link, and consists of a half-rounded head, B, composed of sides a a, (see Fig. 6,) a circular arc, b, two shoulders, c c, and a central tongue or flange, D, with flat sides, and its front edge beveled from above downward and backward to receive the doublebeveled end of the link 0 in coupling, and lift the pin, which afterward falls in one of the openings in the link and couples the cars automatically. The coupling-pin B D is also provided with aliorizontal cap, B. It has been stated above that the holes in the upper and lower faces of the draw-head are of the same half-rounded part B of the coupling-pin from turning on its axis in passing over the curves of the road, and thereby prevent all friction or binding of the tongue D in the holes D in the upper and lower faces of the draw-bars, which arise in a similar construction of coupling-pin which is old, in which the part B is made cylindrical and provided With a beveled tongue. whereby the coupling-pin is raised by the link in coupling. Preferably, to the top face of the draw-bar is pivoted in suitable uprights a lever, 00, which extends out to one side of the car, and is secured to the enlarged part of the coupling-pin B by an eyebolt, through which the inner end of the lever :10 passes, whereby the coupling-pin can readily be .raised and lowered, when desired. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an automatic car-coupling, the combination, with the link 0, double beveled at its ends, asshown, and a draw-bar, A, provided with holes in its upper and lower faces of the same configuration as a horizontal section of the coupling-pin, of a coupling-pin composed of a head, B, having sides a a, circular are I), shoulders c c, and a central tongue or flange, D, having its outer edge downwardly and rearwardly beveled near its lower end, substantially as shown and described.

2. The combination, with the draw-bar A and coupling-pin B B D, having an eyebolt of the eyebolt, substantially as shown and 1 described.
